There's a maxim from electronic consumer equipment development and manufacturing that holds that it's always the cheapest equipment that's at fault, even when it's not. This is generally because people buy a vast flat screen TV that's connected to a receiver or amplifier via a "standard" like HDMI or DVI that doesn't work, and it's inconceivable to them that the more expensive device mightn't be compliant. That sort of issue with IGES is the reason that STEP was developed, but the paradigm seems to be changing, now that Apple and Microsoft develop their OSs, people update their devices and yet seem to me to frequently blame software developers that their SW is incompatible with an OS that wasn't released when they bought it. Not a lot of logic in that premise. What SW do the scanner manufacturers guarantee their device's output is compatible with? There's a simple file splitter called hjsplit that you could use to divide the file into uploadable-size chunks.

One looks to be in ascii and the other binary format. If still an issue, zip and private email me the file.

We should be able to read:

ASCII
BINARY BIG ENDIAN
BINARY Little ENDIAN
